From: Acute abdominal pain in women of reproductive age: keys to suggest a complication of endometriosis
| Â | Ruptured endometrioma | Ruptured corpus luteal cyst |
|---|---|---|
Clinical and biological findings | Fever and leukocytosis common | Fever and leukocytosis rare |
Cyst size | 4–8 cm | 1–4 cm |
Cyst signal | Homogeneous hyperintense on T1 sequence Shading sign | Heterogeneous on T1 and T2 sequences No shading sign T2 dark spot sign Enhanced rim |
Peritoneal fluid signal | High signal on T1W sequences, equal to that of the endometrioma | Low or intermediate signal on T1W sequences |
